Forthcoming programs include Spurlock's "The Failure Club," a documentary series about conquering the fear of failure; "Let's Talk About Love," a weekly relationship show hosted by Nash, and "Ultimate Proposal," which depicts unusual marriage proposals -- including a prospective groom arriving via parachute -- hosted by "All My Children's" Cameron Mathison.

These new Web series are an extension of Yahoo Executive Vice President Ross Levinsohn's strategy to bring more premium entertainment to the Internet portal, which is already among the top online destinations in the U.S., attracting about 178 million monthly visitors, according to measurement firm comScore.

Yahoo has already gained traction with original programming. The company claims its "Prime Time in No Time," a daily video recap of the previous night's prime-time network shows, is among the Web's most viewed original series.

Yahoo also has expressed interest in acquiring Internet television service Hulu, which is owned by News Corp., Comcast Corp.'s NBCUniversal, the Walt Disney Co. and Providence Equity Partners. Preliminary bids for Hulu were submitted earlier this month.

Yahoo's original content play was first reported by the industry trade publication Variety.
